BACKGROUND OF THE INVENTION

The composition of the present invention relates to a quaternaryammonium salt detergent and the use of such quaternary ammonium saltdetergents in a fuel composition to reduce intake valve deposits andremove or clean up existing deposits on the intake valves; and the useof the quaternary ammonium salt in media such as inks, coatings,mill-bases, plastics and paints. For this application the termsdetergent and dispersant can be used interchangeable and have the samemeaning.

It is well known that liquid fuel contains components that can degradeduring engine operation and form deposits. These deposits can lead toincomplete combustion of the fuel resulting in higher emission andpoorer fuel economy. Fuel additives, such as detergents, are well knownadditives in liquid fuels to help with control or minimize depositformation. As the dynamics and mechanics of an engine continual advance,the requirements of the fuel must evolve to keep up with these engineadvancements. For example, today's engines have injector system thathave smaller tolerances and operate at higher pressure to enhance fuelspray to the compression or combustion chamber. Deposit prevention anddeposit reduction in these new engines has become critical to optimaloperation of today's engines. Advancements in fuel additive technology,such as detergents, have enabled the fuel to keep up with these engineadvancements. Therefore, there is a need for detergent capable ofproviding acceptable performance in a liquid fuel to promote optimaloperation of today's engines.

Many formulations such as inks, paints, mill-bases and plasticsmaterials require effective dispersants for uniformly distributing aparticulate solid in an organic medium. The organic medium may vary froma polar to non-polar organic medium. Dispersants containing terminalbasic groups such as poly(lower alkylene)imine chains are well known andare generally prepared by reaction of the polyimine with polyesterchains containing terminal acid groups, the reaction results in amixture of amide and salt forms. However, many of these dispersants havelimited performance towards viscosity and stability properties, whichwhen incorporated into printing inks or paints give the inks and paintswith poor flow characteristics. Therefore, there is a need for adispersant capable of providing acceptable flow characteristics andhaving stability properties.

As used herein, the term “hydrocarbyl substituent” or “hydrocarbylgroup” is used in its ordinary sense, which is well-known to thoseskilled in the art. Specifically, it refers to a group having a carbonatom directly attached to the remainder of the molecule and havingpredominantly hydrocarbon character. Examples of hydrocarbyl groupsinclude: hydrocarbon substituents, that is, aliphatic (e.g., alkyl oralkenyl), alicyclic (e.g., cycloalkyl, cycloalkenyl) substituents, andaromatic-, aliphatic-, and alicyclic-substituted aromatic substituents,as well as cyclic substituents wherein the ring is completed throughanother portion of the molecule (e.g., two substituents together form aring); substituted hydrocarbon substituents, that is, substituentscontaining non-hydrocarbon groups which, in the context of thisinvention, do not alter the predominantly hydrocarbon nature of thesubstituent (e.g., halo (especially chloro and fluoro), hydroxy, alkoxy,mercapto, alkylmercapto, nitro, nitroso, and sulfoxy); heterosubstituents, that is, substituents which, while having a predominantlyhydrocarbon character, in the context of this invention, contain otherthan carbon in a ring or chain otherwise composed of carbon atoms.Heteroatoms include sulfur, oxygen, nitrogen, and encompass substituentsas pyridyl, furyl, thienyl and imidazolyl. In general, no more than two,preferably no more than one, non-hydrocarbon substituent will be presentfor every ten carbon atoms in the hydrocarbyl group; typically, therewill be no non-hydrocarbon substituents in the hydrocarbyl group.

It is known that some of the materials described above may interact inthe final formulation, so that the components of the final formulationmay be different from those that are initially added. For instance,metal ions (of, e.g., a detergent) can migrate to other acidic oranionic sites of other molecules. The products formed thereby, includingthe products formed upon employing the composition of the presentinvention in its intended use, may not be susceptible of easydescription. Nevertheless, all such modifications and reaction productsare included within the scope of the present invention; the presentinvention encompasses the composition prepared by admixing thecomponents described above.
